Fusobacterium nucleatum CTI-6

Fusobacterium nucleatum CTI-6 is a Gram-negative, rod-shaped bacterium that thrives in host-associated environments. As a chemoheterotroph, it derives energy from organic compounds, a trait that aligns with its role in the microbiota of various hosts. This species is classified as an anaerobe, meaning it does not require oxygen for growth and can thrive in low-oxygen conditions. The cells of F. nucleatum CTI-6 typically arrange in pairs and possess a single replicon, indicating a simple genomic structure. This bacterium has two membranes, a characteristic feature of Gram-negative organisms. It does not exhibit mobility, which is consistent with its free-living biotic relationship, allowing it to establish itself within host environments effectively. Fusobacterium nucleatum CTI-6 has an optimal growth temperature of 37°C, placing it within the mesophilic temperature range, which is conducive to growth in warm-blooded hosts. Additionally, it is nonsporulating, meaning it does not form spores for survival under adverse conditions. The presence of flagella suggests potential movement in viscous environments, although F. nucleatum CTI-6 is not mobile in the traditional sense. This bacterial species plays a crucial role in the complex interplay of host-associated microbiomes, contributing to the ecological balance within its habitat. Understanding its traits can inform research on its impact on host health and disease, particularly in the context of oral and systemic infections.
